resulting in severe damage.
Do not underestimate the power of the magnets. If you lose grip the shaft will hit the rear
bearing, which most likely will result in severe damage and, thus, in expensive repair costs...
After maintenance reassemble the pump in reverse order. Do not over tighten the screws, due to the fact that the threads in the case
are made from plastic. The O-rings are made from silicone or EPDM/Viton, depending on the application. As spare parts, only use new
and original O-rings with the proper thickness and hardness. Used O-rings slowly alter their hardness. Always replace with new parts if
disassembled to prolong the life time of the pump. Silicone and EPDM/Viton O-Rings are resistant against acids and bases.
Bearings
The bearings of the 240 and 320 are based on silicium/ carbide (the hardest material after diamond). The front and back bearing are
equal and can be switched. At normal use they will last for life. Both bearings sit in a EPDM O-ring that will adsorb vibrations and keep
the bearing in a exact position. The shaft of the Marine/240/320 is made of wolfram and also acts as a bearing. The 500/900/1500/2200
Watt model have a flat silicium carbide slip bearing that will keep up with the axial and radial forces. These bearings are exchangeable.
These bearings are based on a wet sealant that means that the pump has no seals that can leak. The shafts of the 240/320 watt are
made of an improved wolfram that is seawater resistant. The shafts of the 500/900/1500/2200 Watt are made of 100% pure titanium of
the highest class G5.

Codes
The control panel contains a number of buttons that are activated by default if the activation codes have been entered.
What do these codes provide access to?
There are five different timers available that can be independently programmed, for each season for example.
These timers can be used to set up both the run time and speed. On all pumps, the dry running protection is also activated automa-
tically. This dry running protection only functions above 1,500 rpm. Below this speed the dry running protection will not turn off the
pump when there is no water in the pump. This ensures that the bearings cannot be damaged by dry running.
